**Leinster's forwards hogged all seven tries for themselves in a runaway 50-15 United Rugby Championship victory over the Scarlets at the RDS.** Two slick scores from Johnny McNicholl and debutant Tomas Lezana kept Scarlets in the contest at 29-15, but Leinster powered home with closing tries from replacements Cian Healy and Dan Sheehan (2). A late penalty try had given the hosts a 22-8 half-time lead, and Caelan Doris claimed the bonus point to add to earlier efforts from Ronan Kelleher and the excellent Andrew Porter. Sam Costelow, who struggled last Sunday against Munster, slotted over an early penalty for the visitors. In a pacy start, Johnny Sexton levelled in the seventh minute.
